81309927 ÷ 489 
Our goal is to divide 81309927 by 489.

Let's proceed to step 1:
489 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 489

On to step 2:
When dividing 81 by 489, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 489

Moving on to step 3:
813 divided by 489 is 1 with a remainder of 324.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 489 away from 813, we end up with 324.
Fetch the next digit (0) from the dividend, attach it to 324 and continue: 3240 / 489

On to step 4:
The number 489 fits into 3240 6 times, leaving a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 2934 from 3240 to get 306.
Include the next digit (9) from the dividend after 306, then repeat: 3069 / 489

Moving on to step 5:
489 goes into 3069 6 times with a remainder of 135.
Write down 6 as next digit of the result. 
Result so far: 166.0
Deduct 2934 from 3069 and we're left with 135.
Grab the next digit (9) from the dividend, add it to 135, then carry on: 1359 / 489

Going ahead to step 6:
If we divide 1359 by 489, we get 2 and a remainder of 381.
The next digit of our result is 2. 
Result so far: 1662.0
If we take 978 away from 1359, we end up with 381.
Include the next digit (2) from the dividend after 381, then repeat: 3812 / 489

Going ahead to step 7:
489 goes into 3812 7 times with a remainder of 389.
Write down 7 as next digit of the result. 
Result so far: 16627.0
Subtract 3423 from 3812 to get 389.
Take the next digit (7) from the dividend and append it to 389, then repeat: 3897 / 489

On to step 8:
489 goes into 3897 7 times with a remainder of 474.
Record the quotient 7 as the next digit in the result. 
Result so far: 166277.0
Subtracting 3423 from 3897 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
489 goes into 4740 9 times with a remainder of 339.
Write down 9 as next digit of the result. 
Result so far: 166277.9
Deduct 4401 from 4740 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 10:
When dividing 3390 by 489, we get 6 with a remainder of 456.
Record the quotient 6 as the next digit in the result. 
Result so far: 166277.96
If we take 2934 away from 3390, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 11:
When dividing 4560 by 489, we get 9 with a remainder of 159.
Use 9 as the next digit of our solution. 
Result so far: 166277.969
Subtracting 4401 from 4560 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 12:
489 can be fit into 1590 3 times, resulting in a remainder of 123.
The next digit of our result is 3. 
Result so far: 166277.9693
If we take 1467 away from 1590, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 13:
489 goes into 1230 2 times with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 166277.96932
The remainder is 252 after subtracting 978 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
489 goes into 2520 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 166277.969325
Subtract 2445 from 2520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
The number 489 fits into 750 1 times, leaving a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 166277.9693251
Subtracting 489 from 750 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 16:
2610 divided by 489 is 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 166277.96932515
The remainder is 165 after subtracting 2445 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 166277.96932515 with a remainder of 1.65e-07.
